My pet peeve is entitled guys in suits walking three or four abreast with their hands in their pockets. I get as close to the curb as I can and just before I’m pushed off the sidewalk, I apply a deltoid of fairly impressive size (260 lbs plus overhead presses) to the one next to the curb. I then apologize as much like Uriah Heap as I can manage. I hope it’s a learning experience.
It must very well be a learning experience. They guy on the curb end will learn to position himself near the wall next time and let someone else get the message. :)
